'To allwwm'itmay concern:

V= Be it known that LWILLIAM B. LEONARD, of the city, county,A and State of New York, have invcnteda newand-Improved Apparatus for Registering the Flow and Consumption of Gases and Fluids; and Ido hereby declare that the following isa full, clear, andiexact' description thereof, reference being had to the accom# panying drawings, forming part of this speciiiation, in Which#- Y Figure 1 is a front elevation .of the apparatus, having the sliding door removed to show theinterio'r. Fig. 2" is a 4transverse vertical section of thesame, looking from the left-hand side' of Fig. 2l.4 Fig. 3 is a-front elevation of the working parts of the apparatus, the front' andsides of the case, the dials, and the gearing'for turning the governing-spindlebei ng refiltered. Fig. 4' is a longitudinal vertical sec- .tiohrtaken through the pipe, the cock, and the rfegulating-chamberl Fig.'5 isa section of the looking from -the righthand of Fig. `1. Eight; isa detaehd view of thecatch for keepinfgppen and releasing the valve which closes the pipe on the stoppage "of the operation of themeter. Y "Similar 4letters of reference indicate corre-V sponding parts in each'of the several figures.,4

My invention consists in the employment of certain Amechanism which has a constant mo- Lion at aiuniform speed communicated to it by suitable means, and which communicates motion to an-indicating' apparatus at a speed which is governed by the amount of opening in'a cocker-its equivalent through which the gas or fluid is` passing, the media by'which the motion 1 is` transmitted from the mechanism; above named to the indicating apparatus communicating in 'such' a manner with the cock grits equivalent asto makethe former travel at the greatest speed 'when the latter is wide open, audio stop the former when thelatter iscIOSed, and the lpassage through the latter being of suchform that the-area of its opening 4will always bear'the saine relation to the speed ofthe for'nner.,v

.The amount of gas or fluid of a' certain press-. 4ure whichwi'll pass `through the cock or its equivalent in4 a-given time being ascertained -by any meter, and provision being made for :.equalizing thesaid pressure, if the speed of Vthe irstnamed mechanism is regulated before starting in proper zproportion to'the amount u of gasi'passng through the cock when it iswid and .use my invention, I will proceed ,to 'de-` f scribe its construction and operation.

gas or Huid passes to the point where it is con-` sumed. It is of thecommon form,- ex-cept that the openings avon that side of the plug through- 'which the gas or fluid enters is an oblique or spiral slot, that being, as' I consider', the form best suited for making the amount of opening proportiouate'to the speed ofthe indicators," for which' object its width may be varied, or it may be wider at one end thanthe other. r For sector secured to` the end cock.

C is the regllatingechamber,'through which the gas for duid passes before going through the cock B. .This ismore particularlyapplt cable for gas,and may be dispenscdwith'when the meter is used for water.l It consists of 'a box having a movable cover or front, in which there is a glass window, b, through which the interior may be examined 'without removing it; 1

Dis a valve within the chambenswinging 1 on a pivot or hinge, c, and capable of closing the entrance ofthe pipeA. `A rod, d, -is secured -to its backside, on which there is a movable balance-weight, which has a slight tendency to close it, counter-acting any tendency of the f pressure of the gas to open it too wide. .The

cock consists of a longnarrow slit,l f, in which the point of a wedge, E, of wood or other ma` teral, of 'suicient width to--t easily, is inserted. This wedge is connected'by a small rod withthe valveA D, and is forced by the pressure of the gas on the said valve to'enter A is the pipe which supplies the gas orluid. B is the cock or faucetjthrough which the gas a number of holes corresponding-witlrthe number of burnersplacedin asimilar oblique or spiral line may be used. S. is the ftootlzred ot' the plug of the "exit-opening from the chamber C toward the i front of the disk F, parallel with its face.

I is a spindle hung in suit-able bearings 1n It carries the'sniall wheel J, which lfits to it by ln feather and feathcrwvay, so as to lie-capable of sliding on it, but turning with it. The edge l of this wheel is in'contact with the face of the The spindle I carries also an endless scrcwa', gearinginto t-he teeth of a wheel, i,(see Figs.'1 and 2,) which gearswith a small pinion, k, one-tenth its size, on anotherspindle, while a pinion, m, on its own axis gears into a wheel, Z,

ten times'its size, on another spindle, the three spindles carrying indicators or pointers placed outside a dial-plate, on which are three dials divided iutotenths-one -dial marking'tens, another hundreds, and another thousands of feet; or the dials and gearing of the indicators may be divided in any other` numerical proportion, using any measurement of capacity vas' the unit. l y

K is a'st-ationary bar situated below the spindle Iahd parallel with it. Upon this bar there is a'sliding socket, L, carrying a finger, fn, which fits .in a grooveiu the boss of the small wheel J. Attached to'the socket is the l toothed rack-bar M, sliding in suitable guides.

lIN is the govcrningspindle, which 'is indei pendent of the clock-movement, It carries a pinion, O, gearing in to the rack-bar M, and another pinion, about the samesize, immediately behind it, gearing into the sector S. One pinion may be made to serve for both. It also carries a toothed wheel, P, which stands outside thc case. This gears into a pinion, Q, on another spindle, outside of the case, furnished with a crank-handle, R, and serving to lopen and close the cock. v

c, Figs. 1, 2, 3, is a spindle, hung below the j clocklxnovementand carryinga lever, p, out

side the disk, and a smaller lever, q, behind it. This is for stopping the'clock-nuovenient when theclock B is shut,which is effected by the wheel J,when it is moved to the center ofA the'disk, coming in contact with the lever p and forcing it forward, so a's to bring the ksmaller lever; q, to bear on the balance-wheel T and stop the escapement. "'This may be understood by reference to Fig. 3, where the levers are shown in blue lines.. The lever is held back,when the wheel J is not in contact with it, by a spring.' a, Fig. 3.

a spindle,r, passing through the regulatingchainber, C. rI his spindle carries a small arm, s,within.the chamber,and has a spring, t,coiled round it, the end of which bears against the top of the chamber and always has a tendency to turn the spindle so as to bring the lever U and arm s tol the position shown in red lines in Fig. 4, ad close the valve when the lever is not held back. V

u (shown in, Fig. 2 and also in dotted lines in Fig.3) is a toothed pinion fast upon the dead-spindle o, uponv which theabarrel Gis hnngm Upont-his spindle is .hnnga lever,V, on-whieh there is a stud", w, carrying a loose pinion, y, gearing into u and also int-o the teeth of the sector on the lever U, against which it is held by asp ring, X, at the back of the lever.

1 is a spindle carrying a catch,(seen in Fig. 6,) whose tooth 2 takes into a space between two teeth of the sector on the lever U.4 The lever V bears on the back of this catch and keeps it-in the sector, causing it, in conjunc! tion with the pinion y, to hold back the sectorlever.

above the barrel G,1 and being turned down-y ward toward the barrel.` i

Y is a springsecured at one end to the outer` periphery of the barrel, and at the other endv to the niainspring within the barrel. When the lnainspring is Wound up,thelspring Y4 lies close to the barrel; but when the mainspring is run down the end of thefvspring Y, which is lattached to it,con1es out to the position shown v in red lines in Fig. 4.,v and as 'by the movement of the; barrel, it comes in contact with the pin 3 and throws it up, it turns the spindle 1 and throws back the catch 2 against the lever V,

which overcomes the resistance of the spring vX and removes the pinion y fromthe teeth ofv the said spindle gearing into another wheel attached tothe mainspring, this wheel Z, as Well as the pinion or pinions O, being only confined to the spindle by uspring friction-- clutches, which prevents the overwinding of any of the parts.` Itis intended that the mainspring shall be suliciently wound up to keep the clock goingfor the usual time required by turning the spindle in shutting ofi the gas, so

that the clock will always be wound up,ready for use before opening the cock. The friction-clutches will, however, admitof the stopping of either the pinion O or wheel Z during,

the turning ofthe spindle N, should the wind-y ing npnot be finished before the shutting 0E is complete, or should it be finished before the A cock is completely shut.

On the spindle 1 there is a small stud,-, t 3, standing out from that part of its periphery if IIayixigfullyrv described my sans t l o Indescribing the modus operand-i I will rst suppose the cock shut, iwhen the sector S would be turned a little beyond the position shown by `the 'blue lines in Fig. 3, and the wheel J will be opposite or near the center of Vthefdisk F, wherethere is no motion.

I will then suppose that it is desired to open the cock its full Width. The valve D must first be released (if shut) by drawing back the sectorl. lever U. The spindleN must be turned in the directionof the red arrow in- Fig. 3; when-tbe sectorfS andthe wheel J will be brought to the position shown by redlines, the wheelnbeing near the periphery or edge of the disk, and receiving a rapidV mot-ion, 'which is transmity vted by the endless screwi on its shaft to the4 Tolessen the supf gearing of the' indicators. ply,the spindlemnstbe turned in the direction of the blue arrow, when the sector moves to the .right hand and the rack M to the left, reducing the areav of the opening in the cock andbringing the wheel Jfneare'rjthe 'center of the disk, whereit Vwill receive aslowermotion, the mainspring being wound insv the meantime.: The positions jin'which the cock and wheel are shown in black lines inFigs. 1 and 3 andthe cock` in Fig. 4 represent the l cock about halfopen, the openingain its plug being shownl in that' position by red lines in Fig.v 5; and the opening in the barrel of the cock being representedby dotted lines in the samegur.' Tov shut iii-cf,A thespindle must be turned still farther in the last-named direction', and when the'wiieelreaches about the position shownlin blne' lines it will act upon the leverp and stop the balancewlieel-,iwhich i stops the Whole-movemenuY proceedt'o state what I claim as `nettaa'ndfdcziV siretosecureby Letters Pateut.- Y
